Abstract
Low density parity check (LDPC) codes for wireless communications are constructed to adapt to channel conditions. A method of encoding input bits by an LDPC code to obtain encoded bits is provided. A method of decoding the encoded bits is also provided. The LDPC code has a parity check matrix obtained by lifting a protograph matrix according to a lifting matrix, in which the lifting matrix is based on a polar kernel.
